HYDRANT.

Application led February My invention relates to the type of hydrant shown and described in niy pending application for United States patent filed inlay 2, 1923, No. 636,165, and the particular fi object of my present invention is to incorporate certain improvements in the details of construction which have been suggested by the ldifiiculties arising from the care and use of the hydrant of my former applicalo tion.

The invention consists generally yin various constructions and combinations all as hereinafter' described and particularly pointed out in the claims.

In ,the accol'npanying draw" forming part of this specification,

Figure -1 is a vertical sectional view of the lower portion of a fire hydrant showing my improved waste Water mechanism ap- '30 plied thereto, the waste water port being shown in Vits open position; p

Figure 2 is a siniilarview showing the Vposition assumed by the parts when ,the hydrant valve is opened;

Figure 3 is a sectional view ,on the line 3 3 -of Figure 1;

Figure t is a sectional view on the line l-l of Figure. 1.

In the drawing, I have illustrated the 33 lower porti-on or base 'of a hydrant having the usual inlet opening 6 to which the water main is connected. The upper portion .of

.the base is provided with `an opening 7 to which the stock or body 8 of the hydrant is secured. As shown in Figures 1 and 2, an n annular iange 9 is providedgin the upper portion of the base adapted to form al seat for the packing 11 and a valve seat ring 12.

The seat ring is preferably provided with screw threads 13 and the opening 7 is correspondingly threaded by meansrof which the ring may be securely clamped against `the packing 11 resting upon the seat 9, thereby providing a watertight joint between the ring and the seat. The {iange 9 is suitably .bored to receive the lower-reducedYportionvlt of the seat ring. An annular valve seat is provided at the lower end of the reduced portion 1li .of the ring 12. This valve seat 'n is adapted to engage va suitable .valve 16, preferably of leather, rigidly mounted upon .a valve stein or vspindle 17 by the :washers 1S and 19 andthe nut 21 as shown clearly inv Figure 1.

An important feature` of this invention is 9, 1925. Serial No. 8,041.

the means provided to prevent waste refuse material such as pebbles, sticks and the like, from clogging the waste water port. The seat ring 12 has an inwardly projecting integral lug 23 provided with a bore to receive a plunger 2st preferably cylindrical in form and of any suitable non-corrosive material, such as bronze. This plunger is adapted to slide vertically in the bore of the seat ring below a cross-head or bar 25 which extends transversely of the hydrant and is centrally secured to the valve stem 17. The upperI end of the plunger is adapted to contact with the under side of this crossbar without being attached in any way thereto and consequently the plunger has freedom of vertical movement but is forced down positively in the bore of the seat ring when the valve stem and orossbar are depressed. provided in the `wall of the seat ring in radial alignment with the plunger and vbeneath the bore in the seat ring. This port communicates with an annular groove-27 provided in the wall of the opening 7 and a discharge port 28 is provided in the wall of the hydrant and communicates with the groove 27 for the discharge ofthe waste water. Thus whenthe valve 16 is closed and the plunger 24C is in its raised open position as shown in Figure 17 the waste water contained within the stock 8 ofthe hydrant will flow through the port 26 to the groovev 27 and from thence through the outlet port 28 to drain the hydrant `of the waste water.

In the use of the hydrant with these waste water ports and the plunger for closing the inner port,.T have found that lwaste refuse material such as pebbles, pieces of wood or the like, vwill be carried by the water into` ing-to .the discharge port 26 and ser-ve as a seal orguard therefor preventing waste Inaterial from being carried into and clogging the port. Whenthe plunger moves ,to its .closed position, this reduced'extenson will slide down vand rest upon the top of the hydrant valve and the waste water discharge port will be closedcompletel-y by the kplunger and when .in its closed position, .the pressure ofthe water on the plungerwill 'force it A port 26 is Y against the wall of the port 26 and positively prevent leakage of water therethrough. The seat ring is also provided with upwardly projecting opposed integral lugs 29 having vertical guideways 3l adapted to receive the ends of the crossbar 25. The bar is adapted to slide vertically in these guideways and the valve stem and valve are thereby guided in their vertical movement.

It will be noted in this application that the plunger for controlling the flow of water through the waste port is not connected to either of the parts' of the apparatus by which it is operated. t is a tree or floating member, may rest upon the top of the hydrant valve, positively moved to an open position when the valve is closed, and allowed to drop or be lorced down by the crossbar 25 when the valve is opened. Then the valve is closed and the plunger raised, the waste water may flow freely through the port but the entrance of pebbles or waste material therein will be positively prevented. Upon opening the hydrant valve, the stein and crosshead supported thereby will be lowered and the engagement of the. crossbar or head with the top of the plunger will :torce it down across the entra ce to the waste port, closing it against the entrance of water as long as the hydra-nt valveV is open. As soon as the valve is raised to its closed position, the plunger will be raised again exposing the wastewater port while the extension will prevent the entrance of refuse or pebbles therein.

The plunger being unattached to the moving parts or" the hydrant will not be affected by any lateral twist or strain on the valve stein or the crossbar thereon and hence will always be in condition to properly perform its functions, closing the waste water port when the crossbar descends and the valve is opened and exposing the port to allow the escape of water but preventing the entrance of pebbles or refuse therein when the valve is raised to its closed position.

I claim as my invention:

l. A fire hydrant having a valve and seat therefor, a stein for said valve and a waste water port above said valve and a sliding cut-off for said waste port in the path of said valve to be raised thereby, and means carried by said stem and normally separated from said cut-olf for positively operating it to close said port when said valve is opened.
